Wartsila OD Box Repairs

Marine Power Systems recently attended a vessel that was suffering from excessive oil loss from the Controllable Pitch Propeller (CPP) system. The source of the leakage was found to be the front seal of the Oil Distribution (OD) box. This system controls the distribution of high pressure hydraulic oil to the propeller blades and therefore determines the blade pitch and load on the main engine.

The OD box was fully overhauled on-site and re-installed to the vessel. To consolidate the repair, the vessel was taken for a comprehensive sea trial where the propulsion system was operated up to 100% in both ahead and astern modes. 

Marine Power Systems are able to overhaul Wartsila VL, VO, RO and RB OD boxes along with their respective shaft and propeller systems. The team are also able to overhaul units from manufacturers such as Hundested, Mekanord, Helseth, Pay & Brinke and others.
